Configuration procedure
1. Configure IP addresses for interfaces, and configure BGP and MPLS L3VPN:
2. Configure MPLS L3VPN FRR:
# On PE 1, create a routing policy named vpnfrr to specify the backup nexthop as 3.3.3.3.
<PE1> system-view
[PE1] route-policy vpnfrr permit node 10
[PE1-route-policy] apply fast-reroute backup-nexthop 3.3.3.3
[PE1-route-policy] quit
# On PE 1, configure a routing policy named backup to set the route cost to 10.
[PE1] route-policy backup permit node 10
[PE1-route-policy] apply cost 10
[PE1-route-policy] quit
# On PE 1, enable FRR in VPN 1 and reference the routing policy vpnfrr.
[PE1] ip vpn-instance vpn1
[PE1-vpn-instance-vpn1] fast-reroute route-policy vpnfrr
[PE1-vpn-instance-vpn1] quit
# Apply routing policy backup to BGP routes learned from PE 3 to specify the BGP routes' cost
as 10, so PE 1 will prefer the BGP routes learned from PE 2.
[PE1] bgp 100
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-vpn4] peer 3.3.3.3 route-policy backup import
[PE1-bgp-vpn4] quit
[PE1-bgp] quit
3. Verify the configuration:
